SPECIFICATION forming part of Letters Patent No. 3782?, dated February21, 1883.

Serial No. 251,872. (Xe model.)

To aZZ whom it may concern:

Be it known that I, DANIEL Hanna's, of Hudson, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Making Figured Gossamer RubberGoods, of which the following, taken in connection with the accompanyingdrawings, is a specification.

My invention relates to machines for making iigured gossamer rubbergoods; and it consists in certain novel features of construction,arrangement, and combination of parts,which will be readily understoodby reference to the description of the drawings, and to the claims to behereinafter given, and in which my invention is particularly pointedout.

Figure 1 of the drawings is a plan ofa ma chine embodying my invention.Fig. 2 is a vertical section on line as x on Fig. 1. Fig. 3

is asectional plan ofa portion of the machine, the cutting-plane beingon line 3/ 1 on Fig. 2, with the perforated pattern -belt removed. Fig.1 is a partial vertical section through one of the side frames on linezzon Fig. 1, and illustrating the mechanism for adjusting the tension ofthe pattern-belt.

In. the drawings, AA are the side frames of the stationary sect-ion ofthe machine, said frames being connected together by suitable tie-girts,as shown, and having mounted in bearings thereon the rolls B and Qtheformer being provided with the crank D, by which it may be revolved; orit may be provided with a pulley, by means of which and a belt leadingfrom a main or counter shaft it may be antomatically revolved.

E E represent the frame of another section of the machine arranged to beadjustable to ward and from the frames A A in any wellknown manner, andhaving mounted in bear ings thereon the roll F, as shown. This frame Eis placed at a variable distance from the frame A A,according to thelength of the piece of fabric to be coated with rubber, said piece offabric having its two ends cemented together to form an endless band, G,which is mounted upon the rolls B and F, as shown in Figs. 1 and 2.

The frames A. have fitted thereto, so as to be adjustable in thedirection of the length of the machine, a pair of housings, H H, insuitable hearings in which are mounted the pressurerolls I and 1,between which the upper portion of the endless band of material G passesas it is fed through the machine. The fraincsA are also provided withthe upwardlyprojecting arms A A, in the upper ends of which are mountedone or more rolls, J, as shown in Figs. 1 and 2.

K is an endless band of thin flexible sheet metal, as brass or copper,having cutthrough the same any desired figure which it may be desired toplace upon the rubber-coated goods, said endless band passing betweenthe pressurerolls I and I with the band of fabric G, into close contactwith which it is pressed between said rolls I and I and the roll 13,thence it passes under and partially around the roll 6 and over the rollor rolls J, as shown in Fig. 2.

The housings H H, carrying the rolls I. I, are adjusted to strain ortighten the band K by means of the shaft L, provided with the crank M,the grooved drums or wheels N N, carried by said shaft, the cords orchains O,connecting said housings and drums or wheels and adapted to bewound upon the grooved portions of said wheels, said shaft beingprevented from being turned backward by the engagement of the pawl Pwith the ratchct-wheel P, all as shown in Figs. land at.

R is a doctorplate adjustably secured by the screws S to the framesA A,and provided with the guardfianges 1%,extending therefrom toward therolls I l, and resting at their lower edges upon the fabric G or thesheet-metal band K, near their outer edges, as shown in Fig. 3. v

The operation of coating a piece of fabric with rubber and imprinting orcoloring a series of figures of any desired design thereon go is asfollows: The rolls 1, O, and J, with the band K,being removed from themachine, and

the doctor-plate It being in position with its lower edge pressing uponthe endless band of fabric G, which has been placed upon the rolls 5 Band F, a quantity of the semi-liquid or pastelike rubber is placed uponsaid fabric contiguone to said doctor-plate and between the flanges It,and the roll B is revolved until the fabric G has passed beneath thedoctor-plate a suf- 100 ficient number of times to coat said materialwith the desired thickness of rubber. The doctor-plate R is then removedand the rolls 0, I, and J are placed in position with the band Kthereon, the doctor-plate is replaced, with its lower edge pressing uponthe upper surface of the lower portion of the perforated band K, and aproper quantity of semi-liquid prepared rubber of a different color tothat first placed upon the fabric is placed contiguous to saiddoctorplate and between its flanges, when the roll Bis again revolveduntil the entire surface of the endless belt of fabric G has passedbeneath said doctor-plate, the perforated band K moving in exact unisonwith said fabric and allowinga quantity of the coloringmatter to reachsaid fabric through each of the openings in said band K.

WVhat I claim as new, and desire to secure by Letters Patent of theUnited States, is

1. In a machine for making figured gossamer rubber goods, thecombination, with a pair of rolls constructed and arranged to support,strain taut, and feed an endless band of fabric to be coated, of anendless band having a series of perforations cut through the same andarranged to move in contact and in unison with the fabric to be coated,and a doctor-plate constructed and arranged to press upon saidperforated band, and provided with guardflanges near each end thereof,substantially as described.

2. The combination of the rolls B, O, F, I, I, and J, the perforatedendless band K, the doctor plate R, provided with the guardflanges R,and means, substantially as described, for adjusting the roll I tostrain said perforated band taut, substantially as set forth.

3. In a machine for making figured gossamer rubber goods, thecombination, with a pair of rolls constructed and arranged to sup portand feed an endless band of fabric to be coated, of an endless bandhaving a series of figures or designs cut through the same, a series ofrolls, as O, I, and J, for supporting said band and causing it to movein contact and in unison with said endless band of material, and adoctor-plate, R, constructed and arranged to operate substantially asand for the purpose described.

In testimony whereof I have signed my name to this specification,in thepresence of two subscribing witnesses, on this 8th day of October,

DANIEL HARKINS. \Vitnesses:
